We need more information; since it's surprising to you, it's probably also
a complete mystery to us.  *grin*

Successful bug hunting involves looking at the clues, and keeping our eyes
open.  We need do say exactly why we think there's a bug, what we expected
to see, and what happened instead.  Most importantly, we have to fight the
impulse to make prejudgements on our own code.

Here are a few questions that might help us understand the context of the
bug:  Can you show us the string you printed?  What exactly tried to
execute the image: Python, or the web browser, or...?  At what part of
your program were we in before doing this?  Was this for CGI, or a
standalone program?  What happens when we vary the content of the image
tag?
